| Abstract: | The coverage problems of the wireless sensor networks on the one-dimensional region are mainly studied in this paper.Firstly,the one-dimensional random coverage model is processed for the sensor nodes on the one-dimensional monitoring region,and the formula is given to calculate the node covering probability.Secondly,the method of determining the launching radius of the sensor nodes is studied.It is proved theoretically that the launching radius of the sensor node should be greater than or equal to 2 times to the sensing radius.Lastly,the calculation of the covering number is discussed.Simulation results show that the sensing radius of nodes has significant impact on the covering number and the node covering probability.The result of the study can be the technical specification used in the designing of the sensor networks on the one-dimensional region. |
